electric inline fuel pumps??

Yes I have used it before on my hot street 318 with about 350 hp and a 4 speed a few years ago. I think I actually have a brand new one on the shelf with -6 an conversion fittings if you’re interested. I think the standard in/output on those pumps are a 10mm if memory serves me well.
they push around 60 psi. I have a regulator already. Do they need the return line? Thanks
